GC and DeLORME just released a plug-in for the PN-20 and PN-40 that allows direct download of a cache just like Garmin units.

The new GEO-friendly firmware update (for PN-40) DeLORME is "very close" to delivering will have space for 15,000 characters and other Geo-features. We have been waiting for this update for a while but it seems to be coming to fruition. The GEO-friendly update for the PN-20 will follow the PN-40.

DeLORME is also about ready to release their Cache Register widget. I understand it will replace the Topo 7 interface requirement and with the new firmware will provide a more GEO-friendly GPS.
